Title: A device for inserting carbon and the like sheets for duplicate books
IPC: F01D5/30
Filed: 1930-07-16
Abstract: 365,575. Duplicating-books. FREY, J. REY-, Immensee, Switzerland. July 16, 1930, No. 21474. Convention date, July 16, 1929. Void [Published under Sect. 91 of the Acts]. [Class 16.] A device for inserting carbon and like sheets between the pages of a duplicating-book comprises a spindle rotatably mounted at the outer edge of the book and carrying at its ends two levers provided with means for clamping a carbon sheet thereto. The spindle 7 is rotatably and slidably mounted in eyes 5 which are held under a piece of cardboard glued to the cover 1 of the book, and carries at each end a lever 8 of half-circular cross section provided with stops 9. A wire member 10, hinged at one end to the spindle 7 and provided with a head 13, is adapted to lie in the hollow of each lever 8 to clamp the carbon sheet 14 in position. Hooks 12 for engaging the ends of the clamping- wires 10 are formed from steel wires 11 which are soldered to the sides of the levers 8. In a modification the levers consist of springy material such as sheet steel and are formed into circularly-bent springs which do not meet at the top, so that the clamping-wires can be forced into clamping position. In another modification only one clamping-wire and lever are provided. More than one carbon sheet may be used with the device.

Title: Production of dicarboxylic acid anhydrides
IPC: C07C51/573
Filed: 1959-06-25
Abstract: A process for preparing and separating succinic and glutaric acid anhydrides from a mixure containing succinic, glutaric and adipic acids comprises heating the mixture to dehydrate the succinic and glutaric acids to their corresponding anhydrides, and distilling succinic and glutaric anhydrides with water of dehydration from the mixture as they are formed.  Both anhydrides may be distilled simultaneously or the temperature may be raised in steps so as to separate the succinic anhydride first. Continuous and batch processes are described and adipic acid may be recovered from the tails.  The starting mixture may comprise the residuum, after partial separation of adipic acid by crystallisation, of a cyclohexane oxidation product and may contain aliphatic monocarboxylic acids, nitric acid, nitrates and water, all of which may be removed by heating, and metal ions which may be removed after said heating by flash evaporation of the organics, or before it by ion-exchange methods. Specifications 633,354, 733,968 and 823,487 are referred to.

Title: Improvements in anthraquinone vat dyes and a process of making the same
IPC: C09B3/32
Filed: 1930-07-18
Abstract: Dibenzanthrones.-The brominated Bz2 : Bz21-dimethoxydibenzanthrones obtainable by the process of Specification 205,304, [Class 2 (iii), Dyes &c.], are separated into two components by treatment with sulphuric acid.  The less soluble component, which appears to be a pure brominated Bz2 : Bz21-dimethoxydibenzanthrone dyes cotton in greenish shades decidedly more yellowish and more brilliant than those obtained from the composite product, while the more soluble component, which gives dull dyeings which are not fast to acid, appears to be brominated dihydroxydibenzanthrone formed by demethylation during the bromination process, and can be transformed to a product giving dyeings fast to acid by alkylation.  The separation is preferably effected by fractional crystallization from concentrated sulphuric acid; alternatively, the more soluble component may be extracted from the composite product by treating with sulphuric acid of suitable strength.  Examples are given of the treatment of the product of example 1 of Specification 205,304 and of commercial Indanthrene brilliant green 2G.  In another example, Bz2 : Bz21-dimethoxydibenzanthrone, obtained as described in example B of Specification 181,304, [Class 2 (iii), Dyes &c.], is brominated in sulphuric acid monohydrate in the presence of iodine and the pure brominated product separated from the reaction liquid by dilution with water and addition of sodium bisulphite.

Title: Improvements in or relating to mechanical atomizing, return flow liquid fuel burners
IPC: F23D11/28
Filed: 1950-09-08
Abstract: 696,071. Fluid-pressure servomotor-control systems. BABCOCK & WILCOX, Ltd. Sept. 8, 1950 [Sept. 8, 1949], No. 22176/50. Class 135 [Also in Group XI] A method of regulating hot-gas production by a machanical atomizing liquid fuel burner (see Group XI) adapted to operate with return flow of fuel from a whirl chamber comprises concurrently varying the pressure of fuel supplied to the burner, the pressure at the burner of fuel in return flow from the whirl chamber and the pressure difference between the supply and return pressures so that all three quantities increase or decrease as the burner output increases or decreases. Fig. 4 illustrates a fuel supply system for a plurality of burners 10 in which liquid fuel is withdrawn from a tank 55 by a pump 60 which passes it through a heater 65 to a high pressure pump 70, which delivers the fuel through piping 61, 63, 64 and a control valve 85 to the burners 10, the return flow passages of which are connected by piping 66, 67, 58 and a control valve 90 to the tank 55. The supply and return control valves 85, 90 are adjusted automatically in response to fuel demand, the valve 90 being opened wider on movement of valve 85 towards the closed position, and vice versa. Fluid pressure in accordance with the operation of a control system, applied say to maintain constant the steam pressure of a boiler heated by the burners, is applied through a pipe 81 to a bellows 92 connected through a stem 96 with a valve 95, so that when increased fuel is required the valve 95 is actuated to allow fuel to a cylinder 98 to move downwardly a piston 97 having a rod 93 carrying a bar 94 connected by a link 101 with a lever 82 mounted on an adjustable pivot 83 and carrying at opposite ends the operating members of the valves 85, 90. The lever 82 is thus rotated to open the valve 85 more widely and to move the valve 90 towards its closed position. The bar 94 is also connected by a spring 102 and a bracket 103 to the movable end wall of the bellows 92 so that as the piston 97 descends the spring 102 allows the stem 96 to move downwardly when the demand for increased fuel ceases. Specification 696,072 is referred to.

The byepass is preferably controlled by a needle valve 12 protected from the action of dust by a filter 13.  The reduction in pressure in the chamber 4 may be effected by absorption of the gas in a solid absorbent 8, in a liquid absorbent as described in Specification 292,607, [Class 1 (i), Chemical processes &c.], or by diffusion through another porous member.

Title: Hand operated pressure cleaning and drying guns

Filed: 1962-06-08
Abstract: 972,519. Cleaning vehicles. PORTER & DIETSCH Inc. June 8, 1962, No. 22374/62. Heading B7J. [Also in Division B2] A portable hand-operated pressure cleaning and drying gun (see Division B2) comprises a dual tubular portion 11 including a high-pressure air tube 12 and low-pressure water tube 17 parallel to each other and one bent to communicate with the other at the far end; a pair of valves 21, 27 controlling the tubes 12, 17; a cylindrical nozzle housing 15 beyond the junction of the tubes and common to them and, in the nozzle housing, a venturi body 40 with an adjustable valve member 35. When the valves 21, 27 are operated to admit air and water, respectively to the tubes 12, 17, water issues from the nozzle as a fine spray, to effect cleaning. The flow through the nozzle is controlled by screwing the nozzle along the threaded end of the nozzle housing 15, this action operating the valve 35. The valve 27 is a three-way valve. In one position it supplies water to the tube 17, for cleaning, and in the other position it supplies low pressure air which mixes with the high pressure air in the pipe 12 and results in the issue of drying air from the nozzle.
